Dantonit - Model DantoGran 0/30 - Bentonite Pellet - Brochure

When sealing with DantoPlug bentonite pellets, you get the crucial advantage that the bentonite only really expands once it is in place down inside the borehole. At this point, the extremely dense material expands into any crevices and gaps that may exist in the borehole. The material’s ability to absorb water and swell remains unchanged over time. It is permanent, and the swelling capacity is many times greater than the volume of the void to be filled in order to create a seal.
